I just have a single request... please always take a look on my answers and in case of doubts, I ll try my best to clarify it

My pleasure....

Thank you sir for explaining, I understood.

S3 is a permutation group on say 3 symbols 1,2,3. Then (123) represents a cyclic permutation of 3 length and so is of order 3.....In Z2, 1 bar denotes the residue class of 1, that ...

1) Order of S3 is 6 and that of Z2 is 2, therefore S3 X Z2 is of order 12...... 2) S3 is non abelian implies S3 X Z2 is non abelian....3) Any non abelian group of order 12 is eith...

Ask me your doubt
